Abstract (en)
[origin: WO9600745A2] The present invention provides novel hydrosilation-curable compositions, the cure of which can be monitored visually, comprising: (1) an ethylenic compound; (2) a compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes with light absorption in the visible spectrum that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a precious metal hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the composition can be visually monitored.
